摘要: 基于横向扩散金属氧化物半导体(LDMOS)器件,研制了一款应用于L波段的宽带射频功率放大器。该放大器共由2级放大级联组成,为了实现宽带以及良好的输出驻波,末级功放采用平衡式拓扑电路结构;级间匹配网络使用微带线及电容混合匹配方法实现宽带匹配。最终实测数据如下:频率覆盖0.96 GHz~1.4 GHz,功放整体输出功率达到50 dBm(100 W),功率增益大于30 dB,效率大于45%。功率回退8 dB,输出功率42 dBm时,邻信道功率比(ACPR)为-40 dBC。指标表明功放模块能够很好地应用于雷达和无线通信发射机中。

Abstract: Based on laterally diffused metal-oxide-semiconductor (LDMOS) devices, a broadband RF power amplifier for L-band was developed. The amplifier is composed of two stages of amplification and cascade connection. In order to achieve broadband and good output standing wave, the final stage power amplifier adopts a balanced topology circuit structure; the inter-stage matching network uses the microstrip line and capacitor hybrid matching method to achieve broadband matching. The final measured data are as follows: the frequency covers 0.96 GHz~1.4 GHz, the overall output power of the power amplifier reaches 50 dBm (100 W), the power gain is greater than 30 dB, and the efficiency is greater than 45%. The power backoff is 8 dB, and when the output power is 42 dBm, the adjacent channel power ratio (ACPR) is -40 dBC. The indicators show that the power amplifier module can be well used in radar and wireless communication transmitters.
